Overview
|
|
|
|
|
********
|
|
|
|
|
|
|
|
|
|
This sample allows to test the task watchdog subsystem.

|
Building and Running
|
|
|
|
|
********************
|
|
|
|
|
|
|
|
|
|
It should be possible to build and run the task watchdog sample on almost any
|
|
|
|
|
board. If a hardware watchdog is defined in the devicetree, it is used as a
|
|
|
|
|
fallback. Otherwise the task watchdog will run independently.

Building and Running for ST Nucleo L073RZ
|
|
|
|
|
=========================================
|
|
|
|
|
The sample can be built and executed for the
|
|
|
|
|
:ref:`nucleo_l073rz_board` as follows:
|
|
|
|
|
|
|
|
|
|
.. zephyr-app-commands::
|
|
|
|
|
:zephyr-app: samples/subsys/task_wdt
|
|
|
|
|
:board: nucleo_l073rz
|
|
|
|
|
:goals: build flash
|
|
|
|
|
:compact:
|
|
|
|
|
|
|
|
|
|
For other boards just replace the board name.
